Next week I will be in Chile for the first time. On Monday, July 6, I will give a seminar at the Instituto de Filosofia y Ciencias de la Complejidad (IFICC). The details can be seen on the flyer below:
Then on Friday I will give a mini-seminar on “The key concepts of the enactive revolution”, which will take place at the Department of Philosophy, Universidad Alberto Hurtado, Santiago, Chile.
Time: Friday 10 July, 12:00 – 14:00 hrs.
Participants: Tom Froese (key note speaker), Glenda Satne (Universidad Alberto Hurtado, Chile), and Mario Villalobos (Universidad de Tarapacá, Chile).

On the 5th of June there will be an event on “Mazatec culture, shamanism and sacred plants” at the Autonomous University of the State of Morelos, Mexico.
I have been invited as one of the speakers and my presentation will be about the latest research on the psychological effects of the use of sacred mushrooms.
The title is: “Nuevos estudios sobre los efectos psicológicos de los hongos sagrados: Neurociencia y modelación”.
I propose that we can better understand the latest neuroscientific results about altered brain function, especially related to increased levels of entropy, from the perspective of complex systems theory.

Since the publication of the Turing patterns paper in 2013 I have been involved in several exchanges in order to clarify and expand my ideas. The latest exchange of commentaries has just been published in the Rock Art Research, the official organ of the Australian Rock Art Research Association and the International Federation of Rock Art Organisations.

At the core of this debate is the question over whether rituals involving altered states of consciousness could have played a role in human prehistory, and whether these states necessarily would have required the presence of certain psychoactive substances, and if these substances would have even been available at the time. In essence, my answers are yes, no, but yes.
In this post I previously remarked about my disagreements with the way in which the commentaries about my work had been presented. But I prefer to advance the scientific debate itself, so I will highlight one aspect of Helvenston’s last response that I find intriguing. She notes how it is difficult to explain the presence of extreme rituals, especially those involving partially disabling substances, from an evolutionary perspective.
This ties in with current debates in the science of religion, which tries to explain costly rituals in a variety of ways such as honest signaling and pro-social psychological effects. I’ve been thinking for a while that it is likely that such rituals would have had to have biologically adaptive advantages from the start, perhaps related to a form of neural self-optimization similar to the model presented in Woodward, Froese and Ikegami (in press). This could be a topic of future work.

My review of Giovanna Colombetti’s book The Feeling Body has been accepted for publication in New Ideas in Psychology. Title and abstract are as follows:
Beyond neurophenomenology: A review of Colombetti’s The Feeling Body
I review The Feeling Body: Affective Science Meets the Enactive Mind by Giovanna Colombetti (Cambridge, Massachusetts: MIT Press, 2014, 288 pages, $40.00 hardcover). In this book Colombetti draws on the enactive theory of organismic embodiment and its key concept of sense-making in order to critically evaluate various aspects of mainstream affective science, including basic emotions and alternative constructionist approaches, as well as the cognitivist approach to emotion and appraisal theory. She defends and develops a dynamical systems approach to emotions and emphasizes the need for including more first-person methods of consciousness science in mainstream affective neuroscience. These are valuable contributions to affective science, and they also advance enactive theory. Colombetti’s proposal goes further than standard neurophenomenology in that she appeals to the bodily basis of feeling, thereby requiring a new sort of neuro-physio-phenomenology. Even more radically, she allows that all living beings are essentially affective beings, even those without a nervous system, and that emotional forms could be co-constituted by more than one person.
